I'm looking for a new cloud backup service, one that works on linux/MacOS and with multiple machines. I've heard many mixed things about Backblaze -- ranging from "It's amazing!" to "Use their [pay per GB] buckets unless you are using a single Windows or MacOS computer", to "Other providers are cheaper". Certainly the best in terms of $/GB seems to be OpenDrive's "unlimited" option, which only includes 'no NASes' as a rather nebulous condition.

I'd love to know -- what do other HN users for this? The story author's point about backups only being backups once you've used them to restore really* rings true to me.
